All of a sudden OR (the MONO version) crashes td and I get this error log and I can't figure out what that means. Please could someone in the know help?

Very strange. Can you attach the full logfile?

[Hannes44]

 OpenRailsLog.zip (7.85K)
Number of downloads: 277


Log attached. There are a lot of warnings and errors but I could not see that they were relevant to the crash.

Btw, It would be very helpful, if there existed a helpfile listing the most important warnings and errors and a recommendation how to repair the route. I tried using route-riter, it showed me many problems, but did repair nothing (no new files in the newroute folder).

[Csantucci]

I see no log attached.

It's there.

He has a fairly new, high end machine w/ plenty of RAM.

What I noticed that looked odd was several errors like this one:

Hopw that helps.

Hello Hannes44,
I've reviewed to log.This is reminiscent of what I had to slog through fixing the PRR-East database errors.
Before I could continue the PRR upgrade I had to fix errors just like you are showing. Before I go on there is a bit of disturbing information: After I had gotten rid of all the PRR database errors that showed in the OpenRailsLog.txt file I began PRR upgrade beginning with the removal of all track in the Philadelphia Zoo Interlocking.
When I began rebuilding There were several times new database errors were being introduced. I fixed these, mostly speedpost items and continued. I tested after every edit session using the Open Rails log file(s).At the time I communicated with Goku . . . he suggested changing this datablock

# ROUTE EDIT
#createNewIfNotExist = true
writeEnabled = true
writeTDB = true
useTdbEmptyItems = false  <======<<< DATA CHANGED TO FALSE (default was true)
#deleteTrWatermarks = true
#deleteViewDbSpheres = true

If the TSRE settings.txt file was set to true I was getting random database errors, as said mainly with speedpost items but all interactives were involved. Now due to the atrocious condition of beginning database problems on the PRR-East I've hesitated posting this as there were a lot of database problems on the PRR and I could not say for sure they were all fixed as I was using Open Rails to flag problems ... and it did this very well indeed. So the default setting "useTdbEmptyItems = true
seemed to cause new database errors on the PRR. But I can't say for sure. It may be a problem with the way TSRE handles Empty Items in the database files. It's a horribly complicated process and as I said, no more errors after the empty item was set to false.
This also raises another issue; Empty Items datablocks accumulate in the database files.
No one knows how many are 'bad' but the present PRR has over a thousand and no problem.

Empty Item blocks are generated when an interactive item is deleted. When the next interactive is placed the editor would normally use the EmptyItem block.
The PRR database is >50MB. Maybe TSRE has a problem with this? IDK.

After I set entry to "false" no more errors occurred. After reading this thread and picking through the log I'm wondering if this is a possible TSRE bug. So, what to do?
First off change the useTdbEmptyItems = setting to false.
Then make an attempt to fix each and every database error on the list. Keep some kind of record of what you do . . . a log.

I started at the top of the OR log just below the statistics. a little bit at a time each day . . . took almost a year.
You can make good use of the tools in TSRE; The Hacks menu and the ability to display TDBItems as a black cube that is selectable and deletable. Be very careful using these tools and be sure to have good backups.
Maybe you could post on Trainsim.com. Goku has a forum there.
Good luck.
regards,
vince

Thanks for your suggestions. I even dont have an entry "useTdbEmptyItems" in the settings.txt. But now I've inserted it and turned it to false. And I'm beginning to delete the isolated black cubes.

The empty item setting is valid in TSRE5_v0.69751.exe and I think the prior version also.

If you see a Signal Item (the shape) without a Black Cube unless it is an intended 'dummy' signal, you can delete them also as it's a signal shape without track database/tit entries.
These don't show in the F4 track monitor.

Good backups a requirement here and careful steps. I got through hundreds of these on the PRR you will too but it takes careful work.

vince
